Save This Manual CAUTION, without the safety alert symbol, is used to address practices not related to personal injury. Keep this manual for the safety warnings and precautions, assembly, operating, inspection, maintenance and cleaning procedures. Write the product’s serial number in the back of the manual (or month and year of purchase if product has no number). Keep this manual and the receipt in a safe and dry place for future reference. WARNING! Read all instructions.
Operating precautions 1. Carbon Monoxide Hazard Using a generator indoors CAN KILL YOU IN MINUTES. Generator exhaust contains carbon monoxide. This is a poison you cannot see or smell. NEVER use inside a home or garage, EVEN IF doors and windows are open. 9. Wear ANSI-approved safety goggles, hearing protection, and heavy duty work gloves during use. 10. People with pacemakers should consult their physician(s) before use.
18. Keep the equipment, Engine, and surrounding area clean at all times. 19. Use the equipment, accessories, etc., in accordance with these instructions and in the manner intended for the particular type of equipment, taking into account the working conditions and the work to be performed. Use of the equipment for operations different from those intended could result in a hazardous situation. Service precautions 1. a. Turn the Power Switch of the Engine to its “OFF” position. b.
• Do not smoke, or allow sparks, flames, or other sources of ignition around the equipment, especially when refuelling. • Do not refill the Fuel Tank while the engine is running or hot. • Do not fill Fuel Tank to the top. Leave a little room for the fuel to expand as needed. 10. CAUTION: This generator is not intended to power sensitive electronic equipment* without the addition of an appropriate line conditioner and surge protector (both not included).
AC APPLICATIONS 1. Before connecting an appliance or power cord to the generator: Make sure that it is in good working order. Faulty appliances or power cords can create a potential for electrical shock. 2. If an appliance begins to operate abnormally, becomes sluggish or stops suddenly, turn it off immediately. Disconnect the appliance, and determine whether the problem is the appliance, or if the rated load capacity of the generator has been exceeded. 3. 4. 2.
5. 6. Connect the Generator only to a load or electrical system (120 V~) that is compatible with the electrical characteristics and rated capacities of the Generator. Set up the Generator outdoors in a wellventilated, dry area, away from building air intakes. The Generator should be protected from direct exposure to rain and snow. Do not set up the Generator on a conductive surface such as a metal deck. Operation: 1.

If any problems are found, do not use the unit until properly repaired.
Start Procedure: FIGURE C Before starting the Engine: a. Inspect the Generator and Engine. b. Fill the Fuel Tank (73) with the proper amount and type of unleaded gasoline and 2-cycle oil. (See Figures B and C.) c. NOTE: Only after the Generator has stabilized and is running smoothly should an appliance or tool be plugged into the AC Outlet of the Generator.

in the “RUN” position when starting a warm Engine. (See Figure E.) FIGURE F FIGURE H “ON” “RUN” POWER SWITCH 3. Then turn the Engine Power Switch to its “ON” position. (See Figure F.) RECOIL STARTER HANDLE (42) CHOKE LEVER (82) “CHOKE” 5. After the Engine starts and warms up, slowly move the Choke Lever (82) to its “RUN” position. (See Figure H.) 6. IMPORTANT: Allow the Engine to run at no load until warm (approx. 3 minutes) after each start-up to allow the Engine to stabilize.
Equipment Operation FIGURE J Load And Circuit Breaker: 1. The total combined load through the outlet on the Generator must not exceed the rated maximum power (800 watts) of the unit. FIGURE I RESET OFF 2. Plug the power cord of the 120 volt appliance/tool into the 120 volt AC Outlet on the Generator. (See Figure J.) 3. NOTE: Do not allow the generator to completely run out of fuel with devices attached. A generator’s output may sharply spike as it runs out of fuel, causing damage to attached devices.
FIGURE L “OFF” POWER SWITCH 3. Turn off the Generator’s Power Switch to stop the Engine. (See Figure L.) FIGURE M FUEL SWITCH (80) “OFF” 4. Turn the Fuel Switch (80) to its “OFF” position. (See Figure M.) 5. Allow the Generator to completely cool before storing. REV 09c, 09g, 09k SKU 66619 For technical questions, please call 1-800-444-3353.
about your ability to safely service the equipment or Engine, have a qualified technician service the equipment instead. Specifications Engine Type Air Cooled, 2-Stroke, Single Cylinder, Horizontal Shaft. Engine Starter Type Recoil Starter Engine Power Rating 2.0 H.P. Displacement 63cc Required Fuel Mixture (50:1) 50 Parts 89+ Octane Unleaded Gasoline Mixed with 1 Part 2-Cycle Oil Fuel Tank Capacity 1.1 Gallons Spark Plug Gap 0.028”~0.
Spark Plug Maintenance: 1. Disconnect Spark Plug Wire from end of plug. Clean out debris from around Spark Plug. 2. Using the spark plug wrench provided, remove the Spark Plug. 3. Inspect the Spark Plug: If the electrode is oily, clean it using a clean, dry rag. If the electrode has deposits on it, polish it using emery paper. If the white insulator is cracked or chipped, the Spark Plug needs to be replaced.
Storage 1. Wait for the Engine to cool, then clean the Engine with a clean cloth. 2. When the equipment is to remain idle for longer than 20 days, prepare the Engine for storage as follows: a. Empty the Fuel Tank and drain all fuel lines. b. Clean out area around Spark Plug. Remove Spark Plug and pour one tablespoon of engine oil into Cylinder through Spark Plug hole. c. Reinstall Spark Plug, but leave the Spark Plug Wire disconnected. d. Pull Starter Handle to distribute oil in Cylinder.
Problem Engine will not start Troubleshooting - ENGINE Possible Causes Probable Solutions Fuel Related: Fuel Related: 1. Improper gasoline/2 cycle oil mix. 1. Mix 50 parts unleaded gasoline with 1 part 2-cycle oil. 2. No fuel in tank or fuel valve closed. 2. Fill fuel tank and open fuel valve. 3. Choke not in start position, especially with cold engine. 3. Move choke to start position if engine is cold. 4. Low quality or deteriorated, old gasoline. 4.
Problem Engine misfires Engine stops suddenly Engine knocks Engine backfires Troubleshooting - ENGINE Possible Causes Probable Solutions 1. Spark plug wire loose. 1. Check wire connections. 2. Incorrect spark plug gap or damaged spark plug. 2. Re-gap or replace spark plug. 3. Defective spark plug wire. 3. Replace spark plug wire. 4. Old or low quality gasoline. 4.
